Abstract

La présente invention concerne un procédé permettant d'ajuster les couleurs de pierres présentant une forme trapézoïdale et triangulaire, à l'aide d'une arête courbée, d'une surface plane (une surface arquée, une surface convexe), et d'un trapèze ou triangle de Qianxigong. Les lumières réfléchissantes des pierres dérivées d'un angle du bord du milieu, une petite facette d'une couronne, une petite facette d'un pavillon et une facette supérieure sont ajustées suivant des angles en vue d'être plus visibles. Afin de disperser l'éclat des pierres sur une large portée ou de le concentrer sur une petite portée, la facette supérieure est conçue telle une arête courbée, qui est obtenue en reliant plusieurs petites facettes, la couronne de la pierre est conçue telle une surface plane (une surface arquée, une surface convexe), ou le procédé de Qianxigong est appliqué sur la petite facette et (ou) la facette supérieure, ce qui permet de régler l'éclat quel que soit l'angle et ce, en vue de le rendre plus visible.
